    1 GND Ground (-), internaly connected with Pin 2 on iPod motherboard
    2 GND Audio and Video ground (-), internaly connected with Pin 2 on iPod motherboard
    3 Right Line Out - R (+) (Audio output, right channel)
    4 Left Line Out - L(+) (Audio output, left channel)
    5 Right In Line In - R (+)
    6 Left In Line In - L (+)
    8 Video Out Composite video output (only when the slideshow mode is active on iPod Photo)
    9 S-Video Chrominance output for iPod Color, Photo only
    10 S-Video Luminance output for iPod Color, Photo only
    11 GND Serial GND
    12 Tx ipod sending line, Serial TxD
    13 Rx ipod receiving line, Serial RxD
    14 NC
    15 GND Ground (-), internaly connected with pin 16 on iPod motherboard
    16 GND USB GND (-), internaly connected with pin 15 on iPod motherboard
    17 NC
    18 3.3V 3.3V Power (+)
    Stepped up to provide +5 VDC to USB on iPod Camera Connector.
    If iPod is put to sleep while Camera Connector is present, +5 VDC at this pin slowly drains back to 0 VDC.
    19,20 +12V Firewire Power 12 VDC (+)
    21 Accessory Indicator/Serial enable Different resistances indicate accessory type:
    1KOhm - iPod docking station, beeps when connected
    10KOhm - Takes some iPods into photo import mode
    68kOhm - makes iPhone 3g send audio through line-out without any messages
    500KOhm - related to serial communication / used to enable serial communications Used in Dension Ice Link Plus car interface
    1MOhm - Belkin auto adaptor, iPod shuts down automatically when power disconnected Connecting pin 21 to ground with a 1MOhm resistor does stop the ipod when power (i.e. Firewire-12V) is cut. Looks to be that when this pin is grounded it closes a switch so that on loss of power the Ipod shuts off. Dock has the same Resistor.
    22 TPA (-) FireWire Data TPA (-)
    23 5 VDC (+) USB Power 5 VDC (+)
    24 TPA (+) FireWire Data TPA (+)
    25 Data (-) USB Data (-)
    26 TPB (-) FireWire Data TPB (-)
    27 Data (+) USB Data (+)
    Pins 25 and 27 may be used in different manner. To force the iPod 5G to charge in any case, when 'USB Power 5 VDC' (pin 23) is fed, 25 must be connected to 5V through a 10KOhm resistor, and 27 must be connected to the Ground (for example: pin 1) with a 10KOhm resistor.
    28 TPB (+) FireWire Data TPB (+)
    29,30 GND FireWire Ground (-)
